Neus

Neus (or "Nose" for Dutch impaired people) sniffs the gasses that are sucked out of the klusbunker. It's that little pcb screwed onto the right wall.

Facts

• it uses 7-10 watt (because the sensors have little heaters in them)
• has 8 MQ-sensors
• Arduino based
• talks via an NRF24L01 with the rest of the space
• has a DHT11 for temperature/humidity
• temp/hum may have an offset because they are in the airway and because they are located to 8 heaters(!)

sensors

• MQ-135

who

Initially designed/soldered by Flok. Later on Benadski made some modifications to reduce the detection-range.
